Exodus 16:20-24

20Notwithstanding they hearkened not unto Moses; but some of them left of it until the morning, and it bred worms, and stank: and Moses was wroth with them. 21And they gathered it every morning, every man according to his eating: and when the sun waxed hot, it melted.

22And it came to pass, that on the sixth day they gathered twice as much bread, two omers for one man: and all the rulers of the congregation came and told Moses. 23And he said unto them, This is that which Yhwh hath said, To morrow is the rest of the holy sabbath unto Yhwh: bake that which ye will bake to day, and seethe that ye will seethe; and that which remaineth over lay up for you to be kept until the morning. 24And they laid it up till the morning, as Moses bade: and it did not stink, neither was there any worm therein.
